I am putting together a class/presentation on turbulence. I could use some help finding some videos of the effects of turbulence on skydiving canopies (I don't want to use paragliders or airplanes). Clear air turbulence, mechanical turbulence due to objects on the ground, wake turbulence, dust devils, etc.

If you have found some good ones, please post a link. Note: I would rather not use videos of collapses that resulted in serious injury or fatality. Shock and awe are not what I want to convey with this class.
